LEGO Wah-wah Pedal

Here’s a guitar wah-wah pedal that [Christian Munk] built. Inside you’ll find a circuit board that he etched and populated based on this design but he chose to build the housing out of LEGO. The video after the break gives you an idea of what it sounds like, but for those who’ve stepped on a LEGO piece with bare feet, his pedal pounding might make you cringe!

To manipulate the sound the pedal rocks forward and backward on a center pivot shown above as a grey “nut” sticking out the side of the frame. Inside there’s a system of LEGO gears that turn a trimpot to alter the sound. This might go along nicely with that guitar amp you hacked together.

Probably close to (if not the) best musical talent we’ve seen on HaD. The lego enclosure is novel, but I think he’s barefoot for a reason; I’m betting it would break (or at the least get gross) if he wore shoes while using it. So that kind of keeps it away from any kind of stage use.

Also, I echo @vonskippy’s comment about making real enclosures. If this one was just to make sure the circuit worked, that’s fine, but this won’t last through many performances and should be replaced with something more durable (@ehrichweiss’ idea sounds pretty good; I’d go with that if I couldn’t hack something I had or make one from scratch).
